Application filed August 6, 1912. Serial No. 713,568.

To all whom, it may concern Be it known that I, PAUL B. GLEY, a citizenof the United States, residing at Mystic, in the county of New Londonand State of Connecticut, have invented a certain new and usefulImprovement in Drawing-In Mechanism, of which the following is aspecification, reference being had to the accompanying two sheets ofdrawings.

The object of this invention is to provide simple but effectivemechanism by means of which the operation of drawing the ends of warpthreads through harness may be facilitated; said mechanism havingparticular relation to the operation of selecting and separating theindividual threads as they are needed.

In order to explain my improvement clearly I have provided theaccompanying drawings, in which- Figure 1 is a diagrammatic end view ofa warp beam, lease rods and the customary clamp for holding the bunch ofwarp ends during the drawing-in operation and said view also shows,mounted upon the lower lease rod, a carriage which is one of thefeatures of my present improvement; said carriage being shown, on arelatively larger scale, in Fig. 2. Fig. 3 is a front side elevation ofmy improved drawing-in mechanism, illustrating particularly the mannerof separating the bunch, or group, of threads from the one to be nextdrawn in. Fig. 4: is a top view of wires 19-20 which are described indetail hereinafter.

Referring to these drawings, the numeral 10 indicates a beam of warpthreads, 77 and 12 are rods or rolls over which the said warp threadsare guided, and 13-13 are lease rods around which the said threads arepassed in alternate relation to each other, and 14 denotes the usualweighted clamp for holding the bunch of warp ends; the parts thus fardescribed being substantially as now commonly provided in drawing-inframes.

It is a common practice at the present time for the drawer-in to employan assistant to select the warp threads, one at a time, from the bunchof ends and to hold the selected end at the backside of the harnesswhere the drawer-in can reach it with his hook and draw it forwardbetween the heddle wires, and my present improvement is designed toprovide simple mechanical means for selecting the ends, thus making itpossible to dispense with the services of the said assistant. Themechanism whereby I attain this desirable result is mounted upon thelower lease rod and includes a carriage 15 that is suspended below saidlease rod by means of rolls 16-16, as here illustrated, and saidcarriage is connected with a weighted take-up cord 17 in such mannerthat it (the carriage )will be automatically moved in the directionindicated by the arrow in Fig. 3 of the drawings as fast as the ends aredrawn in to the harness. Fulcrumed at 18, on the opposite sides of thecarriage 15, are levers 19-20 whose upper, free, end portions are bentto form open hooks 19 and 20, one of said hooks being properly locatedto receive the bunch of warp threads from one side of the upper leaserod and the other hook being properly located to receive thebunch ofwarp threads from the other side of said upper lease rod. The lower endportions of the levers 19-20 are extended laterally and are c0nnected,respectively, with foot levers 21-22 in such manner that, when thelevers 21-22 are depressed, the hooks 19 or 20, as the case may be, willbe moved laterally, thus correspondingly moving the bunch of threadsinclosed by said hook. The levers 19-20 are brought back to their normalpositions by springs 23-24 (see Fig. Referring now to Fig. 3 of thedrawings, it will be seen that the threads are in front of the lease rod13 and in the rear of the rod 13 are inclosed by the wire loop 20 andthat the threads that pass from the rear of said rod 13 downward at thefront of rod 13 are inclosed by the loop 19, the threads of the twobunches being crossed at the point a: and said threads are interlaced atthat point excepting the first, or outer, thread, and it will be obviousthat, if the proper hunch is drawn to one side, it will carry with itall of the interlaced threads of the other bunch excepting the saidfirst one, thus leaving that one in its normal, vertical, position,separated from the other threads and in a position where it may bereadily reached by the drawing-in hook and drawn through the harness.The wire loop last in use is then allowed to return to its normalposition and the other loop is used next, thus releasing the firstthread of the other bunch. Thus the threads are separated, one at atime, by simply using the loops alternately, until the warp has all beendrawn into the harness.

Having thus described my invention, I claim as new and Wish to secure byLetters Patent 1. In drawing-in mechanism of the class described, incombination lease rods for dividing the threads into two bunches andinterlacing the same, and means supported from one of said lease rodsfor moving said bunches alternately to release a single thread andseparate it from said bunches.

2. In drawing-in mechanism of the class described, the combination oflease rods for dividing the thread into two bunches and interlacing thesame, and means slidably mounted upon one of said lease rods for movingsaid bunches alternately to release a single thread and separate it fromsaid bunches.

3. In drawing-in mechanism of the class described, lease rods fordividing the threads into two bunches and interlacing the same, acarriage supported upon one of said lease rods, and pivoted hookedmembers movable with said carriage for moving said bunches alternatelyto release a single thread and separate it from said bunches.

4. In drawing-in mechanism of the class described, lease rods fordividing the threads into two bunches and interlacing the same, acarriage supported upon one of said lease into two bunches andinterlacing the same, a a

carriage supported upon one of said lease rods, pivoted hooked membersmovable with said carriage for moving said bunches alternately torelease a single thread and separate it from said bunches, foot operatedmechanism for actuating said hooked members, and means for automaticallyreturningr said hooked members to their normal position.

G. In drawing-in mechanism of the class described, the combination oflease rods for dividing the thread into tWo bunches and interlacing thesame, a slidably mounted carrier suspended from one of said lease rods,a counterweight therefor, and means movable with said carrier for movingsaid bunches alternately to release a single thread and separate it fromsaid bunches as the ends are drawn into the harness.
